Multiquip D4312501003 Hose Radiator Lower - OEM Replacement Part

The lower radiator hose is a critical cooling system component that channels coolant from the bottom of the radiator back to the water pump and engine block on welder units. This hose operates under constant pressure and temperature cycling, making it subject to deterioration from heat exposure, ozone, and coolant chemicals over time. A failing lower radiator hose can lead to coolant leaks, overheating, and costly engine damage if not replaced when signs of wear appear.

Designed specifically for Multiquip welders, this OEM lower radiator hose ensures proper fit and reliable performance in demanding jobsite conditions. Replacement is recommended when hoses show cracking, bulging, softening, or visible deterioration. Regular cooling system inspection should include checking hose condition, clamp tightness, and coolant level to prevent unexpected downtime.

Compatible with the following Multiquip models:

• DLW-400ES
